Sometimes you have to do what you have to do to see if there is a pulse from the developers.
Pretty sure I helped you with another bug a few years ago – also a Javascript issue.
And this time I am pretty sure I have pasted the offending code above.
That’s a start.

LOL I fixed it.And I stand corrected – 1000 apologies!
It would have taken you 5 seconds to fix, not 5 minutes!

Dear Users
In order to get this plugin to stop asking you to delete the plugin after deleting a note, just change the class on line 216 from “delete” which conflicts with the class of the plugin “Delete” button, to something else, also making sure that the new class doesn’t conflict with anything else.

This is the plugin’s wordpress.org repository support page.
By contributing to the solution here I am doing my part.
There was a “problem” and I provided a fully documented solution to you.
And yet you don’t think this is enough.
I don’t agree.
